Problems solved by technology

This has restrictions on the design of the heat sink, and in the housing of the above-mentioned heat sink, only a space is provided to allow the working fluid to flow therein, without restricting the flow direction of the working fluid, which may cause the flow of the working fluid disorder, so that the heat dissipation efficiency of the heat dissipation device 1 cannot be effectively improved

Abstract

The invention relates to a heat radiator and relative producing method, which comprises a case, a heat radiation channel for cycling the working liquid, a reflux channel, the first and second connection channels. Wherein, the heat radiation channel and the reflux channel are on different planes to avoid the turbulence when the working substance is transmitting the heat and the turbulence can reduce the heat radiation efficiency. In addition, said working substance is not needed to be transformed between liquid and gas. Therefore, the invention has wider application.

Description

technical field [0001] The invention relates to a heat dissipation device and a manufacturing method thereof, in particular to a heat dissipation device with a channel through which a working fluid can circulate to achieve heat dissipation and a manufacturing method thereof. Background technique [0002] With the advancement of technology, the number of transistors per unit area of ​​electronic components is increasing and denser, resulting in an increase in heat generation during operation. Therefore, in order to maintain the electronic components at an effective operating temperature, most of the current methods use external fans and cooling fins to deal with the heat dissipation. Since the heat pipe can transmit a large amount of heat over a considerable distance with a small cross-sectional area and temperature difference, and can operate without an external power supply, there is no need to provide power and space utilization considerations Next, the heat pipe is one o...
